Abstract
It is shown that reproduction of sounds from old wax cylinders using various optical methods gives quite excellent materials in optics education. The laser-beam reflection method is explained by the geometrical optics, and is further discussed on the basis of the diffraction theory. Various techniques for improving the quality of reproduced sounds are introduced. Fiber optics is used for reproduction of sounds in a low pressure stylus contacting method. Applications of the laser- beam reflection method to other analogue recordings are introduced.
